What exactly is a carbon price, and how does it work? What would it look like and how would it change everyday life? In this episode of TILclimate (Today I Learned: Climate), MIT economics professor Christopher Knittel joins host Laur Hesse Fisher to break down the complexities of carbon pricing. Together, they explain different types of programs, give us a sense of how much it would cost, and explore how countries and U.S. states are experimenting with carbon pricing now.
Christopher Knittel is a professor of applied economics at MIT’s Sloan School of Management, director of the MIT Center for Energy and Environmental Policy Research (CEEPR), and co-director of the MIT Electric Power Systems Low Carbon Energy Center. Prof. Knittel’s research focuses on energy and environmental economics, and he works to compare the efficiency and costs of different programs and policies that aim to reduce greenhouse gas emissions.
